問題文
A regional health information exchange assigns one continuous series of numbers to specimen containers that are recorded across three different tables. Two extra requirements apply: a batch process must reserve five consecutive numbers in one call before it writes any row, and the series must restart from its starting value once a configured ceiling is reached. Which two capabilities of a sequence object address these requirements? (Select two.)
選択肢
- sp_sequence_get_range can retrieve several numbers in the sequence at once.
- A sequence can be defined to restart the number series when a specified number is reached.
- A sequence automatically protects its values from being changed after they are inserted into a table.
- A sequence guarantees that the numbers actually stored in the tables contain no gaps.
- A sequence enforces uniqueness of its values across the tables that share it.
